Pond Liner Installation Guide

Site Considerations

Whenever possible, site selection should avoid areas where flooding or ground water pressure can occur. The lining “bottom” should be well above the water table. If the site selected is in an area where organics are in the soil, or if gases can be generated by chemical reaction, the design must allow for venting.

Surface Preparations

Surfaces should be level and free of all sharp rocks (all rock and stone greater than .05 diameter), objects, vegetation and stubble. (Soil sterilization may be necessary to kill roots and certain types of grasses.)
The subgrade surface should provide a unyielding foundation for the VeerKisaan Pond Liner with no sharp or abrupt changes or break in grade. Proper compaction assures stability and support of the liner.
Rough ground and standing water, mud, snow – any excessive moisture – is counter productive for liner deployment.

Controlling Groundwater

Groundwater should be taken into account and, if present, it will need to be controlled both during and after construction. One method for controlling groundwater is to develop a French drain system under the lining that allows the water to flow laterally under the lining without floating the lining.
A good design for an under drain is to pipe it to the outside of the lake into a gravel sump. This allows the sump to run continuously during construction and, with the placement of an upright at this sump, the under drain can be pumped if needed to relieve hydrostatic pressure and gas buildup under the lining system.

Slopes

Side slopes should be no steeper than 3:1 whenever feasible. Slopes are usually hand-raked to achieve proper smoothness.

Receipt of Liner and Materials

Liner panels are fabricated into large sheets to minimize field seaming. These large panels are first accordion folded, then rolled up on a core.
It is recommended that the liners panels’ protective covering not be removed until installation and that any uncovered panels be stored out of direct sunlight.

Anchor Trenches

To secure the edges of the lining in an earthen pit, an “anchor trench” is dug. Anchor trenches are approx. two foot wide by two foot deep (2′ x 2′) and one foot back from the crest of the berm (standard trench dimensions and depth vary according to project design.)
Dirt removed should be raked out flat on the far side of the trench, away from the pit, to be used to backfill after the liner edges are laid out in the anchor trench, while allowing the panels to be unrolled along the berm. Slightly rounding corners of the trench avoids sharp bends in the VeerKisaan Pond Liner. The trench itself needs to be free of loose soil and rocks.

Site Structures

Structures, piping, concrete, drains, and any associated work should be completed prior to lining installation.

Liner Deployment

The roll is raised by a loader, forklift, or other lifting equipment, and then unrolled in one direction, and unfolded in the other direction.

Panel Placement

Take time when unloading and placing rolls of lining to avoid damage. Verify the location of a panel or sheet before unrolling and placement to avoid improper alignment. Sandbags are required to keep the panels in place during installation, exposed or covered. Care should be taken to avoid wrinkles in the seam areas and around mechanical attachments.
It takes considerable manpower to deploy a liner. It is “pulled” but not stretched. Minor wrinkles insure the liner is installed in a relaxed condition.
A ballast system (sand bags) and anchor trenches are used for all VeerKisaan Pond Liner installations.

Field Seaming

The lining material itself determines the types of field seaming techniques used. The most commonly used process is heat fusion welding, which can be done with hot air or hot wedge.
